SPECIFICATION forming part of Letters Patent No. 656,219, dated August 21, 1900.

Application filed July 22, 1899. Serial No. 724,774. (No model.) A

To all whom it may concern: I

Be it known that I, WILLIAM L. ScHEL- LENBACH, of the city and countyof Philadelphia, in the State of Pennsylvania, have invented an Improvement in Seat Structures, of which the following is a specification.

- My invention relates to seat structures specially adapted for car-seats; and it consists of the improvements which are fully set forth in the following specification and are shown in the accompanying drawings.

A part of my improvements relates toaseat structure having a shifting back, and consists of improvements in the means for shifting the back and causingit to maintain the proper angle of inclination. In carrying out this part of my invention I connect the shifting seatback with the stationary frame by movable shifting side arms, to which the seat-back is pivoted, and by means of suitable powertransmitting devices between thestationary frame and the seat-back the latter is rocked on its pivotal connections with the side arms and is caused to assume the proper inclination. In the specific embodiment of this part of my invention, as hereinafter set forth, these power-transmitting connections consist of rotary shafts journaled in the side arms and geared to the seat-back and stationary frames, respectively.

Another part of my invention relates to the means of supporting the seat-back with reference to the stationary frame by means of supporting devices between the back and frame and embraces the'feature of the adj ustability of said supports, whereby the an- I gnlar inclination of the seat-back maybe varied and the seat may at will be transformed into a reclining-seat.

Another part of my invention relates to an improved foot-rest construction especially frame and cushion.

tion. 'Fig. 2 is a longitudinal vertical sectionalview on line A A, Fig. 1, with theseatback shifted to the intermediate position. Fig. 3 is a side elevation of the seat-cushion Fig. 4 is a vertical sectional view on the line B B, Fig. 1. Fig. 5 is a side elevation illustrating a different form of my invention, and Fig.6 is a longitudinal vertical sectional View of the same with the seat-back shifted to the intermediate position.

1 l are the side f rames,\vhich,\vith the pedestal or base, constitute the stationary frame of the seat structure.

2 is the seat-cushion frame, which carries the seat-cushion 3.

4 is the seat-back.

5 5 are movable side arms pivoted at one end to the side frames 1 1 and at the other end to the end of the seat-back near the base. In the construction shown the arms 5 5 are connected by the pivots 6 6 with the metal frames 7 7, secured to'the ends of the seatback.

J ourn'aled longitudinally in the arms 5 5 are shafts 8 8, provided at their ends with bevelgears 9 10, engaging racks 11 12 on the seatback and side frames, respectively.

As the seat-back is shifted by swinging the arms 5 5 on their pivots 13 13, the shafts 8 are rotated by the gearing 1O 12, and motion is imparted through the gearing 9 11 to the seat-back, which is rocked upon the pivots 6 6 and caused to assume the proper angle, as shown in Fig. l.

The seat-back is supported in its positions at either side of the seat-frame by fingers 14 14, carried by the seat back and fitting notches or seats 15 15 at each end of the side 0 frame.

It is sometimes desirable to increase the inclination of the seat-back and use the structure as a reclining-seat. For this purpose the notches 15.15 are made adjustable, so that the point of support for the fingers 14 14 may be shifted. In the construction shown in Figs. 1, 2, and 4 the notches 15 15 are extended to a substantial extent inwardly, and adjustable supports 16 are employed, extend- 10o ing into the notches and forming by their projections 17 the inner ends of the supporting-sockets for the fingers 14. (Dotted lines in Fig. 1.) By adjusting these pieces 16 the inner supports for the fingers may be moved inwardly and the seat-back caused to assume a greater angle of inclination. This is permitted by so arranging the gears 10 and 12 that they will move out of mesh when the side arms 5 5 are in extreme shifted positions. The pieces 16 may be adjusted and locked in position by any suitable means. As shown, they are provided with a series of teeth 18, adapted to engage a tooth 10 on the side frame. A spring 20, acting on the piece 16, serves to hold it-in engagement with the tooth 19 while permitting longitudinal adjustment.

When the seat structure is used as a reclining-seat, it is desirable that it should be provided with foot-rests, and such a construction is shown in Figs. 1, 2, and +1. I employ a transversely and bodily movable foot-rest carrier, which, as shown, consists of bars 21 21, guided on the side frames 1 1 and carrying the foot-rests 22 23 at their ends. As the seat-back is shifted the carriers 21 21 are shifted transversely in the frames 1 1, so as to project at the front of the seat, as shown in Fig. 1, with the foot-rest 22 in position to sustain the feet of the occupant of the seat. hen the seat-back is shifted to the other side, these movements are reversed, and the bars 21 21 are projected at the opposite side, with the foot-rest 23 in operative position. Suitable means may be employed for moving the carrier when the seat-back is shifted. In the particular construction shown the carrier consists of curved racks engaging toothed wheels 24, journaled in the side frames 1 1 and carryingpinions 25,which engage toothed segments 26 on extensions of the rocking arms 5. When the foot-rest at one side is fully projected, the opposite foot-rest is preferably withdrawn under the seat-cushion, so as to form no obstruction atthe rear of the seat. In the construction shown the foot-rests 22 23 are pivoted to the ends of the carriers 21 21, and the foot-rest at the back passes into sockets 27 in the side frames.

Suitable means are employed for shifting the seat-cushion when the seat-back is shifted. In the construction shown the seat-cushion frame 2 is provided on each side with a notched projection 28, which engages a pin 29, carried by the rocking arm 5, as by the segment extension 26. As the arms 5 are rocked in shifting the seat-back the seat-cushion is shifted longitudinally on the guides 30 of the side frame by the action of the pins 29 in the notches 28.

In Figs. 5 and 6 I have shown a rocking foot-rest 31, which is operated by the rocking arms 5 5. In this case the foot-rest is carried by arms 35, pivoted, as at 32, to the side frames 1 1 and provided with notches 33 33, which engage pins 3% on extensions of the arms 5 5. As the arms 5 5 are rocked in shifting the seat-back the arms 35 35 and footrest 31 are rocked, so that the foot-rest will at all times assumea position at the back of the scat, leaving the front free and unobstructed.

The details of construction which have been shown may be varied without departing from the invention.

What I claim as new, and desire to secure by Letters Patent, is as follows:

1. In a seat structure, the combination with the stationary frame, and shifting seat-back,

of movable shift-ing side arms, between the stationary frame and seat-back, to which said seat-back is pivoted, power-transmitting connections between said stationary frame and seat-back to cause the seat-back to rock on its pivotal connection with the side arms when said side arms are rocked, and independentlyadjustable supports between the seat-back and stationary frame at each side for supporting the seat-back when it is shifted with provision for adjustment to vary its angular position.

2. Inaseat structure, the combination with the stationary frame, of a shifting seat-back, a foot-rest movable transversely with reference to the stationary frame when the seatback is shifted, and oppositely-acting powertransmitting connections between the seatback and foot-rest for moving the foot-rest in a direction opposite to that in which the seatback moves, whereby the foot-rest is always brought into a position at the front of the seat structure opposite to the position occupied by the seat-back.
